Does the passive ability of target creature get replaced by this? Thought it does make sense for flying creatures to lose their flight when frightened.
Yes, previous passives will be removed, so this can also be used as a counter to Pests, Salvagers, SoFr, Voodoo Dolls, etc.
Hmmm... Interesting... So, Skeletons will be frightened and couldn't revive as living creatures? How ironic.
